From ca217d041639883ffcc1c7f7856502efca1b90a4 Mon Sep 17 00:00:00 2001 From: Craig Robbins Date: Tue, 27 Jan 2015 00:39:33 +1000 Subject: [PATCH] Revert "Fix a crash (assert) when client set serial version < 24 in INIT command SER_FMT_VER_LOWEST is set to zero, then the test is stupid in INIT because all client works. In mapblock we check if client's serialization version is < 24, but if client sent serialization version < 24 (15 for example) the server set it and tried to send nodes, then BOOM" nerzhul is (may?) be working on a new solution. For the moment this is reverted because old worlds cannot be loaded (see discussion on github for the commit).
